Natural Movement
Hardware
The first portable device that allows you to enter virtual reality
Complete ceiling-mounted rotary encoder with tensile cable system
Freedom to Move
Traditional VR forces you to teleport or use joysticks, breaking immersion and causing motion sickness. OpenDeus solves this with a simple, elegant solution: a ceiling-mounted rotary encoder that tracks your natural walking motion through a tensile cable system.
Walk naturally in a 25 square foot space. The system intelligently maps your movement to infinite virtual distance. No treadmills. No sliding. Just walking—the way humans were meant to move.
Precision Tracking Technology
At the heart of the system is a precision rotary encoder with a metallic tracking ball. As you move, the ball rotates, sending real-time positional data through the integrated green PCB to your VR headset.
The system measures strain on the rope and reads vibrations continuously. Your character in the game only moves when you're actually moving—eliminating false inputs and ensuring perfect synchronization between your body and your virtual avatar.

Engineered for Simplicity
Unlike complex treadmill systems with motors and gears, OpenDeus relies on proven rotary encoder technology, basic physics, and smart software.
Fewer moving parts means higher reliability and dramatically lower cost.
Tool-Free Installation
Clean your ceiling surface, position the industrial-grade suction mount, and press the button. That's it—the system is ready to use.
Supports up to 300 kg (660 lbs) of load. No drilling. No permanent mounting.
Maximum Portability
Moving to a new apartment? Take it with you. Want to use VR at a friend's house? Bring the system in a small carrying case.
Works on any smooth ceiling surface. True plug-and-play portability.
Complete System in a Briefcase
The entire OpenDeus system packs into a single briefcase, making it the most portable high-end VR solution ever created.

WITH FEET TRACKERS
While other VR treadmill systems cost $1,000–$3,000 and require dedicated rooms, OpenDeus delivers superior natural movement for a fraction of the price.
This is movement hardware designed for everyone, not just wealthy enthusiasts.
Safer Than Walking in the Real World
The rope holds you up—if you stumble, it catches you. If you lean too far in any direction, the rope gently guides you back to center.
